In the form shown in Figures 1 and 2. the insert is sprung into the channel 15 with the ends of the arms of the U formation coacting with the shoulders 16 and the intermediate part of the U formation thrusting against the bottom of f erably located at the end of the rib and coactsr with the intermediate part of the U-shaped formation of the insert 17. Usually the bottom rail of the sash is provided with a rubber weather strip 22 as shown'in Figure 3, and the bottom rail, when provided" with the weather strip 22 is formed slightly different from the stiles 5.

` Thev formation of the sash of sheet metal, pei se forms no part of this invention.

As seen in Figures 4 and 5, the sill 23 is formed with a vprojecting rib 24 and the bottom m1 formed with a channel and insert 25 similar to the insert 17, and also the rib 24 is tapered or wedge shaped instead of being rectangular, as shown in Figure 2, for the purpose of guiding the channel i the bottom rail onto the guide rib -and spreading the insert 25.

In Figure 5, the end of the rib is shown as abutting against the intermediate part of the U formation of the insert 25.

In-'the form shownin Figure 6, the sheet metal sashframe member 26 is provided with a sheet metal channel shaped insert 27, and the weather strip insert 28 is mounted therein and secured to the insert 27 by suitable means as rivets 29.v

In this form shown in Figure 6, the entrance' of the channel is not contracted and the edges of the insert are exposed at the entrance of the channel. Also, the edge of the rib 30 is formed rounding at 31 instead of square as at 21.

In Figure 7, the insert is composed of two sections 32, 33, these being arranged astride a flange 34 on the walls of the sash member, which anges are opposed to and parallel to the front and the rear wall of the sash member. The rib 35 is shown as provided `with shoulders 36 near the base thereof for thrusting against the edges of the weather strip sections to hold the sash members off the window frame or the base flanges of the rib and also to hold the sash from undue lateral movement. In any form of this invention a weather strip insert including fibrous material and a spring backing is housed entirely within the sash member and coacts with a window guide or rib to render the sash weather tight and antirattling and to hold the sash from undue lateral movement, and out of metal to metal contact with the frame.

The inserts 13 at the upper and lower ends of the stiles are arms of a corner iron insert, the other arms 1?, 13b of which extend into the top or bottom rail.

The weather strips or inserts 17 are insertable in and removable from the channels by an endwise sliding movement and are insertable and raii, is removed. In sashes of this type, one of the sash members, usually the bottom rail, is removable for the purpose of replacing a broken glass. The bottom rail is removable by first removing the fastening members or screws 40 which pass transversely through the stiles 5, and through the portions of the inserts 13 in the stiles. so that the bottom rail with the corner irons can be pulled outwardly and separated from the stiles. When so separated, the inserts 17 in the stiles 5 can be removed and replaced by an endwise movement.

Also, in the form shown in Figure 6', the channels 27, which carry the inserts 28, can be moved and replaced in a similar manner. If an insert is used in the bottom rail, it can be removed and replaced by an endwise movement when the bottom rail is separated. If an insert is used in the top rail, the top rail is removable the same as the bottom rail, in order to remove and replace bottom rail, unless the insert that extends across the end of the other is split or provided with a passage. If the inserts in the stiles extend across the ends of the insert in the bottom rail, said inserts in the stiles would be provided with a passage alined with the passage of the insert inthe the bottom rail. Likewise, if the insert in the bottom rail extended across the lower end of the inserts in the stiles, said insert in the bottom rail would be split or provided with a passage for the guide or rib 2 as seen in Figure 9.

when a. rubber buffer strip 22 is used in the bottom rail, it and the fibrous inserts 17 in the stiles are beveled at their ends to conform to the miter joint between the stiles and the bottom rail (Figure 1).

Sashes are usually provided with latches at the lower corners thereof, and these are carried by the bottom rail in order to be readily removable therewith.

45 designates a latch or bolt located internally of the sash and extending within the bottom rail.

46 designates a plate mounted on the outside of the inner wall of the bottom rail and formed with a lift ange 47, this plate being provided with an offset portion 48.

49 is an angle lever pivoted at 50 at its angle to the plate 46 and having one arm 51 located in the offset portion 48 and the other arm extending in juxtaposition to the lift flange to act as a finger piece or as a pinch handle. The arm 51 located in the oiset portion has a pin 53 at its end extending through a slot in the wall of the bottom rail and the pin coacts with a passage 54 in the shank or rod part 55 of the bolt 45.

As before stated, the bolt slides in an enlarged portion 13b of the corner iron located in the bottom rail and is spring pressed outwardly by a spring encircling a stem 55 of the bolt, the spring being located between the inner end of the bolt and the end wall of the part 13b, which houses the bolt. The bolt extends through an opening 56 provided in the lower end portion of the insert 17 and coacts with notches in the ribs 2. The arm 13b of the insert and the plate 46 are secured to the bottom rail by fastening members or screws similar to the screws 40. These fastening members are preferably composed of two sections, one being a sleeve screw 57 and the other a stud screw 58 threading into the sleeve screw.

During the operation of the pinch handle lever 49, obviously, the bolt will be withdrawn and by removing the fastening members 40 and withdrawing the bolt 45 so that its end clears the opening in the weather strip insert 17, the bottom rail can be removed and also the weather strip insert 17 removed and replaced by an endwise movement.

What I claim is:

l. In a window construction, the combination of a window frame having inwardly projecting guide ribs, of a sash having each of its stiles formed with a lengthwise -channel opening through its outer edge at the side edge of the sash, the channel receiving one of the ribs, an insert housed in the channel and engaging opposite sides of the rib, a latch including a member housed within the bottom rail member of the sash and movable transversely of the adjacent channel into and out of engagement with the adjacent rib, the adjacent insert being provided with an opening through which the latch member extends, the latch member being retractable out of said opening for permitting the removal and replacement of the insert, the bottom rail being removable carrying the latch mechanism therewith for permitting the removal and replacement of the inserts by an endwise movement of the inserts out of and into the channel.
